摘要： A door interlock assembly is for a draw-out circuit breaker assembly. A draw-out circuit breaker is housed within an enclosure including a door and includes a poleshaft operable between first and second positions corresponding to separable contacts being opened and closed, respectively. The door interlock assembly includes a pivot member coupled to the poleshaft and a door latch interconnected to the pivot member by a linkage, such as a threaded drive rod. The door latch pivots such that a first end thereof engages and locks the door of the enclosure when the poleshaft moves to the second position. An optional mechanical sensor assembly adapted to trip the circuit breaker when the door is positioned in any position other than closed, is also disclosed.
